Abstract
The present invention relates to a spray of microjets emanating at an inclined angle from nozzles comprised in a substantially planar membrane layer. A spray nozzle unit for spraying a plurality of fluidic microjets from a pressurized liquid comprises a substantially planar (semiconductor) support having an upstream surface and a downstream surface, and a spray membrane layer arranged on the downstream surface of the support. The spray membrane layer comprises a plurality of nozzle orifices each configured for spraying a fluidic microjet in a Rayleigh regime. Thee support defines a cavity extending from the upstream surface to the spray membrane layer. The cavity is in fluid communication with each one of the nozzle orifices for supplying the pressurized liquid to the nozzle orifices. A position of the nozzle orifices, seen along a direction perpendicular to the downstream surface, is offset in respect of a centre of the cavity. At least two of the nozzle orifices exhibit a different offset in respect of the centre of the cavity.
